He isn't a guy who transforms it by his performance. Frankly, any speedster that can catch 2 or 3 balls a game removes the safety from the equation, which means we can get more one on one opportunities with Fitz and Floyd..THAT is what transforms the offense. You can't double or even help on both of those guys, and it's truly pick your poison. And it's something that we've missed forever...but in Arians offense that component is very important.
If it were just that though, it's not enough to justify Ginn's contract. But the KR/PR skill makes it a great fit and gets Badger and PP off of special teams. Win win win all around.
